The present invention pertains to a method for carrying a bag 100. The method comprises the steps of lifting the bag 100 by a top handle attached to a top gusset 7 of the bag 100. The top gusset 7 of the bag 100 comprising a top right side and a top left side. The bag 100 comprises a front gusset face 17 attached to the top gusset 7. The bag 100 comprises a back gusset face 8 attached to the top gusset 7. The bag 100 comprises a right side gusset 12 having a perimeter with piping. The right side gusset 12 has a right gusset top 60.

The bag 100 comprises a bottom gusset attached to the front gusset face 17, back gusset face 8, right side gusset 12 and left side gusset 13. The top gusset 7, front gusset face 17, back gusset face 8, right side gusset 12, left side gusset 13 and the bottom gusset together forming a skin 40 that envelops the frame 50, the right gusset top 60 extending onto and overlapping the frame top 52, the left gusset top 62 extending onto and overlapping the frame top 52. the frame top 52, the left gusset top 62 extending onto and overlapping the frame top 52. There is the step of moving the bag 100.

The present invention pertains to a carrying bag 100. The bag 100 comprises a frame 50 having a top gusset 7. The bag 100 comprises a skin 40 for the frame 50. The skin 40 has a top gusset 7, and a right side gusset 12 and a left side gusset 13 which extend onto and overlap the frame top 52 so there is not a 90 degree corner formed between the top gusset 7 and the right and left side gussets 12, 13.

In the operation of the invention, the bag 100 differs from other cut-and-sew gusset constructions on the market with its unique contoured construction. The side gusset is constructed into the top gusset 7 of the bag 100 as most gussets are separated from the top gusset 7 of the bag 100. Traditional/longbound construction as well as sidebound construction use two or three pieces of material held together, respectively, with piping and separated into top gusset 7 and left and right side. This new gusset construction also uses three pieces of material help together by piping but incorporates the top gusset 7 with the two side pieces. The bag 100 deflects abrasion and wear at the corners better than traditional cases with their 90 degree corners. FIGS. 7 and 8 show both front and back perspective views, respectively. The back section of material of back gusset face 8 is wrapped around to the top gusset 7 of the bag 100 to connect with piping 10, piping 11, right side gusset 12 and left side gusset 13. Top gusset 7 can also be connected to back gusset face 8 if this is not already one whole piece. Handle cup 20 is an exterior locking handle than top gusset 7 and back gusset face 8 will be all one piece. If handle cup 20 is an interior zip-away handle cup (as shown), then top gusset 7 and back gusset face 8 are separate. Piping 10 and piping 11 is stitched to hold top gusset 7 together with right side gusset 12 and left side gusset 13. Piping 10 and piping 11 can be comprised of PVC piping or PVC piping covered in the main material of the bag 100. Right side gusset 12 and left side gusset 13 are the side gussets that make this design different from all bags on the market currently. Right side wheel 14 is riveted to back gusset face 8 and right side gusset 12. Left side wheel 15 is riveted to back gusset face 8 and left side gusset 13. PVC moisture barrier 16 is sewn to back gusset face 8 and is held in place with piping 10 and piping 11. Front gusset face 17 is held in with piping 10 and piping 11 and is sewn to top gusset 7. Side carry handle 18 is riveted to right side gusset 12. Side feet 19 are sewn on to left side gusset 13. PVC skid bar 9 can be sewn to the top gusset 7 and back gusset face 8. Top carry handle 21 is riveted or sewn on to top gusset 7.

In the manufacture of the bag 100, the gusset is sewn together from three different pieces. These pieces are the top/back, the right side and the left side. The pieces are all held together with piping. The piping can either be PVC or PVC covered in main material. The material can be polyester, nylon, cotton, poly/nylon blend, poly vinyl chloride or poly propylene.

The sides of the gusset are cut in a way that they integrate into the top gusset 7 of the bag 100 and actually become part of the top gusset 7. After these pieces are sewn together, the skin 40 is wrapped around a frame 50. This frame 50 can either be Honeycomb ABS, PP, PVC or a metal frame with PE board 58 reinforcements, as shown in FIGS. 9 and 10. This frame 50 is what gives the bag 100 its structure and the skin 40 is just a covering that does not give any structural aid.
